Answer:

The scientist can use only the angle x and the distance y to calculate the distance between the Earth and the Sun using the cosine function.Step-by-step explanation:

The cosine of an angle is equal to the ratio of the length of the adjacent side and the length of the hypotenuse. In equation form:

cos x = BC / y

Solving for BC

BC = y cos x

BC is the distance between the Earth and the sun

What equation is equivalent to 9x - 3 = 729? 9x - 3 = 981 9x - 3 = 93 3x - 3 = 36 32x - 3 = 36
lilavasa [31]

Answer:

Option 2nd is correct

9^x-3 =9^3

Step-by-step explanation:

Given the equation:

9^x-3 = 729

We can write 729 as

729 = 9 \cdot 9 \cdot 9 = 9^3

then;

9^x-3 =9^3

Therefore, the equation which is equivalent to 9^x-3 = 729 is, 9^x-3 =9^3

\frac{-18}{-3} (divide 3 from numerator and denominator) = \frac{6}{1} = 6

\frac{2}{7} × \frac{8}{3} = \frac{16}{21}

\frac{3}{8} +  \frac{1}{12} =  \frac{9}{24} +  \frac{2}{24} =  \frac{11}{24}

Hello! I need some help figuring out the following parts of trigonometry. Since this is a rather difficult math term to understa
Zina [86]
Alright so these ratios have many different forms but the way I use to remember the trigonometric ratios is:
SOH
CAH
TOA

This means:
Sine --> Opposite/Hypotenuse
Cosine --> Adjacent/Hypotenuse
Tangent --> Oppositie/Adjacent

With that in mind, number 1:
Would be Sine, or C.

Number 2 would be, Cosine, or E.

And number 3 would be Tangent, or B.

Hope that was helpful.
